Stability and surface diffusion at lithium-electrolyte interphases with connections to dendrite suppression [PDF]

arXiv, 2015
This work presents an ab initio exploration of fundamental mechanisms with direct relevance to dendrite formation at lithium-electrolyte interfaces. Specifically, we explore surface diffusion barriers and solvated surface energies of typical solid-electrolyte interphase layers of lithium metal electrodes.

Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams

Advanced Functional Materials, EarlyView.
Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...

Tackling activity-stability paradox of reconstructed NiIrOx electrocatalysts by bridged W-O moiety

Nature Communications
One challenge remaining in the development of Ir-based electrocatalyst is the activity-stability paradox during acidic oxygen evolution reaction (OER), especially for the surface reconstructed IrOx catalyst with high efficiency.

Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

Advanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.

Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

Advanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

First-principles calculation of the stabilities of lithium garnet compositions against hydration [PDF]

arXiv, 2016
A series of density functional electronic structure calculations were carried out to better understand the crystallographic factors governing the stability of LinA3B2O12 lithium garnet phases against hydration. The reaction studied is H2O + LinA3B2O12 = LiOH + HnA3B2O12. Most of the compositions are stable against pure water; the main driving force for

NOTES ON LITHIUM. [PDF]

JAMA: The Journal of the American Medical Association, 1894
When Augustus Arfvedson, a Swedish student at Upsala, presented to his friend and teacher, the celebrated Berzelius, the new substance that he had separated from the rare granitic mineral petalite , found at the mines of Utoe in Sweden and which he had determined to be an alkali, he requested Berzelius to suggest a suitable name for it.
